Learn about the geometry of HyperMesh in these tutorials.

**HM-2010: Import and Repair CAD**

In this tutorial you will learn how to import and repair CAD.**HM-2020: Generate a Midsurface**

In this tutorial you will generate a midsurface.**HM-2025: Auto-Midsurface with Advanced Extraction**

In this tutorial you will use auto-midsurfacing with advanced extraction options.**HM-2030: Simplify Geometry**

In this tutorial you will change the shape of parts and simplify geometry.**HM-2035: Refine Topology**

Topological details of the geometry may affect the quality of the mesh created from the surfaces.**HM-2040: Create and Edit Line Data**

Sometimes CAE users need to create models from sketches where there is no pre-existing geometry. The tools in this tutorial will help you accomplish that task.**HM-2050: Create Surfaces from Elements**

The surfaces created in this process are regular surfaces that can be used for geometry editing (for changes to a design) and meshing, and to export geometry information (in reverse engineering applications, for example). This is particularly useful if you are trying to obtain geometry information (surfaces) from a model containing elements only.**HM-2060: Create and Edit Solid Geometry**

The use of solid geometry is helpful when dividing a part into multiple volumes, for example, to divide a part into simple, mappable regions for hex meshing.**HM-2070: Edit Geometry and Mesh Using Quick Edit Panel**

This tutorial will explore the geometry and mesh editing functions available in the Quick Edit panel.**HM-2080: Modify Models using solidThinking Inspire**

The benefit of using solidThinking Inspire is that you can apply quick geometry fixes without going back to the CAD software.**HM-2090: Edit Dimensions**

In this tutorial you will learn how to create and edit dimensions on geometry using the Dimensioning tool.
